GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(247, 771) = 190437
GCD(247, 771) = ( 247 x 771 ) / 190437
= 247 / 771
= 247
Step2:
LCM(1, 778) = 778
GCD(1, 778) = ( 1 x 778 ) / 778
= 1 / 778
= 1
Step3:
LCM(1, 743) = 743
GCD(1, 743) = ( 1 x 743 ) / 743
= 1 / 743
= 1
So, Greatest Common Divisor of 247, 771, 778, 743 is 1
